U+2206 Increment

U+2206 was added in Unicode version 1.1 in 1993. It belongs to the block U+2200 to U+22FF Mathematical Operators in the U+0000 to U+FFFF Basic Multilingual Plane.

This character is a Math Symbol and is commonly used, that is, in no specific script. The character is also known as Laplace operator, forward difference and symmetric difference (in set theory).

The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it acts as Other Neutral. When changing direction it is not mirrored. The word that U+2206 forms with similar adjacent characters prevents a line break inside it. The glyph can be confused with one other glyph.

The CLDR project calls this character “increment” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: triangle.

The Wikipedia has the following information about this codepoint:

∆ may refer to:

  • Triangle (∆), one of the basic shapes in geometry. Many different mathematical equations include the use of the triangle.
  • Delta (letter) (Δ), a Greek letter also used in mathematics and computer science
  • Delta baryon (Δ), one of several Baryons consisting of up and down quarks.
  • alt-J (Δ), a British indie band
  • Laplace operator (Δ), a differential operator
  • Increment operator (∆)
  • Symmetric difference, in mathematics, the set of elements which are in either of two sets and not in their intersection
